A stroke occurs when the blood supply to a part of the brain is reduced severely. This causes the brain tissue deprived of oxygen and other essential nutrients. Soon within a few minutes, the brain cells begin to die. A stroke is a medical emergency and requires an immediate treatment.
A stroke occurs when the blood supply to a portion of the brain is disturbed, causing it deprived of oxygen and nutrients. The brain cells starts dying within a few minutes of the stroke. Stroke affects the arteries connecting to and within the brain. It can be a serious, life-threatening, medical emergency.
Symptoms of stroke may vary and depend on which portion of the brain has stopped functioning due to reduced blood supply. Patients may exhibit varying symptoms such as discussed in this article. The symptoms of a TIA or a mini-stroke are the same as those of a stroke.
Stroke treatments work by either opening the blockage or treating the rupture, which are the main causes of a stroke. Advances in the medical science in the last decade have significantly improved survival rates after stroke. The chances of survival of a person are much better now if the stroke is diagnosed and treated immediately.
